What is harness OSA?

[funfall 0]

What is the "OSA" in harness measurement, and its significance? "Over the shoulder"? Search turned up nothing else useful. Can't reach our rigger for a few days. Thanks.

I don't know, but it's in the "office use only" section so don't worry about it. Your measurements go below.

I see it in specs for some used containers, and new stock containers, but don't know what to make of it. Most seem to be OSA 0 or +1. I assume it affects proper fit. If I order custom, I won't be as concerned about it.

Oh, in the stock list, it says that it means "over the shoulder extension." I still don't know what that means though.

But if you want to order a stock rig, call them and talk about the size.

+1 means the yoke is 1 inch longer on each end. The 3 ring will be 1 inch farther over the shoulder.

Make sense?

My grammar sometimes resembles that of magnetic refrigerator poetry... Ghetto

The OSA is an extra inch per number +1= 1 extra inch, +2 =2 extra inches.... in the yoke. it is designed for people with larger chests to keep the tightness off the shoulders and to keep the 3 rings and chest strap in the proper postion (lower). Please call me (or Mike Maguire) at UPT if you need a further explaination.

Thanks all. So it's a yoke dimension, rather than harness.

Pretty much. There are slight changes to the harness, but it is mostly just a change in the yoke.
